Physical Science

Brandy Velten (doctoral student) and Dr. Kenneth Welch (Comparative Physiologist) from the University of Toronto wanted to know whether birds with very different speeds at which they flaps their wings (i.e. wingbeat frequencies) had correspondingly varying types of myosin proteins in their muscles.
